FENCE.

SPECIFICATION forming part of Letters Patent No. 519,995, dated May 15, 1894.

Application filed February 10, 1894. Serial No. 499,789. (No model.)

To 0%.? whom it may concern:

Be it known that I, DANIEL D. FRIsBEE,a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Fences, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention consists in the peculiar construction of a wire fence comprisinga number of separated wires stretched between posts, tied together at intervals by stays and having suitable tension devices.

The invention further consists in the peculiar construction of the tension devices and the construction and application of a spring applied to the Wires separately for permitting expansion and contraction of the wires without danger of breakage, and further in the peculiar construction, arrangement and combination of the various parts.

In the drawings, Figure 1 is a side elevation of a section of fence embodying my invention. Fig. 2 is an enlarged perspective view of one of the tension drums showing the lock therefor removed. Fig. 3 is an end elevation thereof showing the lock applied to the shaft thereof. Fig. 4 is a perspective view of the spring as in use. Fig. 5 is a longitudinal section therethrough showing in full and in dotted lines different positions of Fig. 6 is a perspective view of a section of the fence, illustrating the construction of the stay. Fig. 7 is a plan of the top and bottom wires of the fence showing the manner of attaching the stay to such Wires.

A represents the end posts of the fence and B one of the intermediate posts supporting the wires D which may be secured thereto in any suitable manner such for instance as by staples E.

F is a brace preferably consisting of two boards arranged on opposite sides of the wire of the fence and bolted together through the fence notched into the upper end of the end post A at the upper end and resting upon a stone G at the lower end, the lower end being tied to the end post by means of a tie wire H.

Upon the outer face of the end post A I secure a series of brackets I in which are detachably journaled the winding drums J, having suitable apertured lugs K to which the the stay wires intersect.

end of each fence wire may be secured. The winding drum is provided with a suitable shaft having the squared end L projectingbeyond one side, the bracket I next the squared end of the shaft is provided with the beveled ters the dovetail groove formed by the lips M, as shown in Fig. 8, thereby firmly locking the drum from unwinding. Thus when the proper tension has been put upon the wire of the fence by turning the winding drum and winding the wire about it, it may be locked in position by inserting the key M as described.

The stay I form as shown in Fig. 6, usinga single Wire and bending it at the points where the fence wires are to cross it to form an olfset shoulder O and a loop P extending up from said shoulder, the intervening vertical portions or b being sufliciently out of line to permit of the passage between the loop and such vertical portions of the fence wire, as plainly shown at the lower part of Fig. 6. The stay may then be secured uponthe fence wire by bending down the loop P over the fence Wire beside the vertical portion a, thus forming an eye. The top and bottom wires are provided with the bends Qshown in Fig. 7, forming an indentation at each point where The upper ends of the stay wires are left plain and are engaged with this notch or bent and then formed into a coil R about the top and bottom fence wires, as plainly shown in the drawings, thereby preventing the sliding through the stay wires of these upper and lower fence wires, while the intermediate fence wires are free to slide through the eyes formed in the stays as described- Each fence wire I preferably form to inclu de a spring of peculiar construction, shown particularly in Figs. 4 and 5 to maintain a constant tension upon the wires and to take up the expansion and contraction thereof. These springs I make of a single piece of flat metal bent into substantially the shape of an S with the two ends overlapping the center and having apertures S formed in the ends and in the center in line with each other,

through which from opposite directions I pass two ends of the fence wire securing them by forming eyes '1 on the outer face of the ends, as shown in Figs. 4: and 5. Now it is plain, the parts being thus constructed that tension being put upon the fence Wire will shorten the S longitudinally, forcing it into the shape shown in dotted lines in Fig. 5, and thereby putting the spring under greater ten sion and yet allowing sufficient play for any expansion or contraction which may take place in the wire insuring a substantially even tension on the wire at all times.

What Iclaim as my invention is- 1. A fence comprising end posts, the fence wires severed and having overlapping ends, the S-shaped springs connecting the severed ends, the winding drums on the posts to which the ends of the wires are connected, a squared end shaft for the drum, a bracket in which the shaft is journaled, inclined lips on the edges of the bracket, and the detachable key having the beveled edges which engage said lips and having a slot in which the squared portion of the shaft engages, substantially as described.

2. In a fence,'thecombinati0n of a fence wire formed in two parts having overlapping ends, an S shaped spring apertured at its ends and center to permit the passage of both ends and means for securing the ends of the wires to opposite ends of the spring, substantially as described. ,7

In testimony whereof Iaifix my signature in presence of two Witnesses.
